But not every politician is blindly ideological like Obama. Vitor Gaspar, Portugal’s Finance Minister, is willing to admit error. Here are some relevant excerpts from a New York Times report.

Unlike Obama, willing to admit mistakes

Mr. Gaspar, speaking to The New York Times last week, has a message for observers who say Europe needs to substantially relax its austerity approach: We tried stimulus and it backfired. Like some other European countries, Portugal tried what Mr. Gaspar called “a Keynesian style expansion” in 2008, referring to a theory by economist John Maynard Keynes. But it didn’t turn things around, and may have made things worse.

Why does the Portuguese Finance Minister have this view? Well, for the simple reason that the economy got worse and more spending put his country in a deeper fiscal ditch.

The yield on Portuguese government bonds – more than 11 percent on longer-term bonds — is substantially higher than the yields on debt issued by Ireland, Spain or Italy. …The main fear among investors is that Portugal is going to have to ask for a second bailout from the International Monetary Fund and the European Union, which committed $103 billion of financial aid in 2011.
